The upper part of the lower metering component 16 is placed with a product to be measured.

[0032] The upper working plate 7 and the lower working plate 8 are arranged in parallel.

[0033] The structure of the upper metering component 14 is as follows: It includes an upper connecting sleeve 1407 fixed to the upper working plate 7 by fasteners. A floating positioning block 1401 is installed in the middle of the upper connecting sleeve 1407 through a first round wire spring 1402. An upper floating sleeve 1403 is fitted and installed outside the upper connecting sleeve 1407. The top surface of the upper floating sleeve 1403 and the bottom surface of the upper connecting sleeve 1407 are connected by a plurality of upper springs 1405. An upper base 1404 is fitted and installed at the bottom of the upper floating sleeve 1403.

[0034] The upper base 1404 is locked with the floating positioning block 1401 by fasteners.

[0035] The sensor bracket 13 is fixed to the upper connecting sleeve 1407. An upper proximity sensor 1406 is installed on the upper working plate 7 beside the sensor bracket 13.

[0036] The structure of the lower metering component 16 is as follows: It includes a lower connecting sleeve 1608 fixed to the lower working plate 8 by fasteners. A sleeve 1604 is installed in the middle of the lower connecting sleeve 1608 through a second round wire spring 1603. A connecting rod 20 is fixed to the sleeve 1604. A fixed block 19 is provided on the bottom surface of the lower working plate 8. A lower displacement sensor 9 is installed on the fixed block 19. The connecting rod 20 corresponds to the lower displacement sensor 9. A central shaft 1602 passes through the center of the sleeve 1604. The top of the central shaft 1602 is connected to the lower base 1601. At the same time, the lower base 1601 is installed on the top surface of the lower connecting sleeve 1608. A plugging cylinder 11 is installed on the bottom surface of the lower working plate 8 through a Z-shaped plate 10. The output end of the plugging cylinder 11 is connected to the central shaft 1602. A lower floating sleeve 1605 is installed outside the lower connecting sleeve 1608.

[0040] During the actual working process:

[0041] First, prepare the equipment. When the upper metering component 14 and the lower metering component 16 are in a separated state, place the calibration block 21 on the lower base 1601 and perform calibration first. After calibration, place the product to be detected (such as the impeller 15) on the lower base 1601.

[0042] Place the impeller 15 on the lower base 1601. At this time, the lower floating sleeve 1605 is in the floating state, and the lower base 1601 does not contact the impeller 15.

[0043] Then, start the equipment to work, drive the pressing cylinder 1 to work, the piston rod of the pressing cylinder 1 extends, driving the entire upper metering assembly 14 to move downward until it contacts the product. The product is subjected to a downward pressure, the lower spring 1606 is compressed, the product moves downward and contacts the lower base 1601. At the same time, the central shaft 1602 is driven downward until the lower spring 1606 is completely compressed. The lower proximity sensor 1607 senses that the position of the lower floating sleeve 1605 is in place. At the same time, the displacement action of the central shaft 1602 will also drive the connecting rod 20 to move downward and touch the lower displacement sensor 9, then the measured height of the product can be fed back and recorded. If the measured value is consistent with the value of the calibration block 21 (within the tolerance range is considered consistent), it means it is a qualified product.

[0044] The above working process of the present utility model can be fully automated for loading and unloading with a robot.

[0045] The overall working reliability of the present utility model is good, the working efficiency is high, the metering is accurate, and the product qualification rate is guaranteed.
